I’ve used several different Zigbee motion detectors and I’ve had issues with all of them:
The Samsung one seemed to work fine for a while, but the battery life seems to be horrible.
I picked up some of the Bosch motion sensors at deep discount and was hoping the fact they took 4 AA batteries would mean battery life would greatly exceed the Samsung sensor but they seem extremely defective. They might work okay for a couple days, but then constantly report motion. Changing the batteries may for a short period of time, but they simply do not function well for any amount of time. I tried the Ikea Tradfri motion sensor for a while, but it seemed to be just slightly worse than the Samsung motion sensor.
Is there a more dependable motion sensor, either Zigbee or wifi?
Ideally something that doesn’t take expensive/small-capacity batteries, possibly AC or USB powered instead.
